智能变电站故障识别及隔离装置设计与功能实现

Design and Function Realization of Intelligent Substation Fault Identification and Isolation Device

为进一步提升煤矿供电系统的稳定性,保证煤矿生产的安全性和可靠性,在分析智能变电站基本结构和未来智能变电站发展趋势的基础上,研究供电系统的特征,而后,基于区域集中控制技术设计了煤矿穿越性故障和不正常运行状态识别和隔离装置,并分别提出过载、欠压、过压和短路等故障的识别方法和所有故障隔离的算法。

To further enhance the stability of the coal mine pow er supply system,ensure the safety and reliability of coal mine production,based on the analysis of the basic structure of intelligent substations and the development trend of future intelligent substations,the characteristics of the power supply system are studied.Subsequently,based on regional centralized control technology,identification and isolation devices for coal mine transient faults and abnormal operating states were designed,and identification methods for faults such as overload,undervoltage,overvoltage,and short circuit were proposed,as well as algorithms for isolating all faults.
